BEST MODES FOR CARRYING OUT THE INVENTION

Referring to the embodiment shown in FIGS. 1-4, there is provided an implement 1 for picking up and removing pet excrement from a surface. Implement 1 is primarily aimed at cleaning flat surfaces, which are the common public ground in which removal of pet feces mostly needed and in which avoidance of such removal is embarrassing or even illegal. Implement 1 comprises a tension member 3 to which a disposable flexible sheet 5 may be coupled so as to form an edge 7 of sheet 5 that is led by tension member 3. It will be appreciated that the term “tension member” refers to any member that functions in a similar way, such as bands, ribbons, straps, strips and the like. Sheet 5 is preferably removable from implement 1 in order to provide easy and neat disposal thereof when sheet 5 is soiled with pet refuse, without defiling other components of implement 1 or the user hands. The combination of sheet 5 and tension member 3 allows isolation of the pet excrement from a surface. An example of such an isolation is shown in FIGS. 1-4. Such an isolation is provided by grip means 11 for gripping and moving implement 1 by the hand of the user, and slip means 13 for slipping or sliding sheet 5 between the pet excrement and the surface to be cleaned. To this aim, string 3 is maintained by slip means 13 in a tautly stretched configuration while tension member 3 is in close contact with the surface, and wherein slip means 13 may be moved by grip means 11 while keeping tension member 3 in close contact with the surface. It is clearly apparent that tension member 3—due to its inherent thinness—will easily lead sheet 5 below the excrement to be removed, so long as tension member 3 is kept stretched and proximate to the surface and is pushed or pulled from its sides through the area in which the excrement is positioned on the surface.

Sheet 5 may be coupled to tension member 3 in a variety of methods. A most simple method may pertain to simple folding of sheet 5 about tension member 3. Such a fold also allows easy removal of sheet 5 from tension member 3 so that tension member 3 may remain attached to implement 1 for further use while a new sheet 5 replaces the formerly removed sheet 5. A permanent thermal welding of sheet 5 to the tension member 3 or adherence of sheet 5 to tension member 3 will usually require removal of tension member 3 together with sheet 5 and disposal and replacement of both with a new set of tension member 3 and sheet 5. Sheet 5 may comprise a polymer, preferably a thermoplastic type, which is available in the market, inexpensive and may particularly adapt for the purposes of this invention. In particular, sheet 5 may comprise a self-clinging wrapping nylon sheet, such as used for household food wrapping, so that when sheet 5 is folded about tension member 3, its self-clinging retains it attached to tension member 3. A roll of sheet 5, such as roll 15 shown in FIGS. 10 and 11, may also comprise perforated cutting lines apportioning it into easily-separated detachable portions, so that each portion may be taken out and either removed for installment in implement 1, as in FIG. 1, or—if roll 15 is held by implement 1, removed simultaneously from roll 15 and implement 1 for disposal, as in FIGS. 8-12.

Tension member 3 may comprise a polymer, preferably a thermoplastic type, or a metallic wire, all of which may adapt for a “permanent” tension member 3 that is installed in implement 1 for repeated operations or for a disposable tension member 3 that is replaced after each use.

Referring again to the embodiment of FIGS. 1-5, sheet 5 may also be intersected into portions, each such portion comprises two plies 17 and 19, connected along their edges 21 to from a bag like section 23. Plies 17 and 19 are disjoined from each other to form a separated mouth section 25. One ply of the two plies 17 and 19 in mouth section 25, such as ply 17, may be enfolded about section 23, and the other ply (19) may be coupled to tension member 3.

Implement 1 may comprise grip means 11 in the shape of an arcuate support member 27, across the tips 29 of which, tension member 3 may be stretched. Arcuate support member 27 may also comprise a handle portion 30 coupled thereto, as in FIG. 5, and which may be removable therefrom. Preferably, arcuate support member 27 comprises a flexible elongated bar being substantially straight when in a non-operative mode, as in FIG. 3. Support member 27 may be bent by the user to form a bowed bar, as in FIG. 1 and so retained through its operative mode by means of tension member 3. This may be accomplished by bowing support member 27 while tension member 3 is being attached to tips 29 when tension member 3 is loose. When support member 27 is relaxed, tension member 3 stretches to holds support member 27 in a slightly reduced bowed configuration (FIG. 1).

Referring now to FIGS. 6 and 7, a variation of the embodiment of FIG. 1 is shown. Implement 1 comprises bipod like casing members 31, across the free ends 33 of which, tension member 3 may be stretched. Casing members 31 are hingedly connected to each other and to the grip means 11, at hinge 35. Grip means 11 may simply comprise an elongated handle that may be locked in its operative position through suitable locking means (not shown). Casing members 31 and elongated handle (means 11) may collapse to be aligned side by side in the stored position, as in FIG. 7. Casing members 31 extend to one direction and elongated handle 11 to the opposite direction when implement 1, is deployed in its operative mode, as in FIG. 6. Casing members 31 further comprise spacing means 35 for keeping them apart when deployed in their operative mode. Such spacing means may include a resilient spring, such as spring 37, or other means such as calibrating threaded nut and bolt mechanism (not shown).

Referring again to FIGS. 1-4 an example of slip means 13 is shown. Slip means 13 comprise two tabs 39 attached to the ends of tension member 3, respectively, and mating notches 41 disposed in arcuate support member 27 and allowing removable respective nesting of tabs 39 thereinto so that notches 41 hold tabs 39 in a snap-fit engagement. Obviously, notches 41 are distanced from each other so as to retain tension member 3 in a stretched configuration when tabs 39 are nested therein. Preferably, each tab 39 comprises a tapered end 43, at which tension member 3 is attached. Tapered end 43 protrudes from arcuate support member 27 toward the surface when the implement is held in an operational mode for picking up and removing pet excrement. Tips 29 of the arcuate support member 27 are preferably rounded or tapered as well. The tapering or rounding of tips 29 and especially tabs 39 facilitate the maneuvering of tension member 3 in close proximity to the ground when implement 1 is moved, allowing the arcuate support member 27 to be held in a continuous variety of inclinations, as the user holding implement 1 finds preferable at the particular moment of moving implement 1.

In reference to FIGS. 8-12, another embodiment of implement 1 is shown. Grip means 11 comprise an elongated hollow tubular body 43. Tubular body 43 is having an apertured end 45 and is so sized to be comfortably held by a human hand (FIG. 8). Tubular body 43 is adapted for containing a roll 15 of sheet 5 wherein an end 47 of sheet 5 may be unrolled and drawn out through apertured end 45. Slip means 13 comprise two forwardly extending securing arms 57 which are coupled to tubular body 43, by support members 49 and along which sheet 5 may be expanded. The securing arms 57 comprise spikes 51, which spikes 51 are spaced apart at a distance corresponding to the width of sheet 5. Tension member 3 is stretched at edges 53 of securing arms 57 at a distance from spikes 51 adequate for containing pet excrement, wherein a drawn out portion of sheet 5 may be pierced once at its sides 55 by spikes 51, stretched from spikes 51 to tension member 3 and folded about tension member 3 to stretch back toward spikes 51 and pierced again by them to form a two ply extension of sheet 5, stretched between spikes 51 and tension member 3.

Securing arms 57 are distanced from each other at a distance corresponding to the width of sheet 5. Spikes 51 are mounted in registration on securing arms 57, adjacent to apertured end 45 of tubular body 43, and tension member 3 is stretched between the free ends 53 of securing arms 57.

Further preferably, slip means 13 comprise a rigid strap 59 curving around tubular body 43 so as to snugly engage tubular body 43 in a friction tight engagement, and wherein support members 49 are firmly attached to the ends 61 of strap 59.

Optionally, apertured end 45 of tubular body 43 comprises a lid 63 having a threaded sleeve 65 adapted to its screwing in a mating threaded end portion 67 of tubular body 43 or its apertured end 45. Lid 63 may further comprise a centrally apertured extension 69 through which sheet 5 may be passed in a contracted manner, the extension being externally threaded and adapted to its partial or full closure by an internally threaded compatible cap member 71.

Spikes 51 may comprise a pair of cone shaped spikes having their base side 73 mounted on securing arms 57, correspondingly, and a groove 75 cut around each of spikes 51 at a distance from its peak 77. The single pair of spikes 51 may serve for hooking both plies of sheet 5—the upper and the lower, at once. But for further comfort in hooking the lower ply of sheet 5, spikes 51 may comprise another pair of spikes 79, so that one pair (spikes 51) protrudes upwards and the other pair (spikes 79) protrudes downwards.

It will be appreciated by those skilled in the art that although the invention was described above in reference to structural elements, it also inherently discloses a method for picking up and removing pet excrement from a surface. Such a method comprises the steps of providing a flexible sheet 5, coupling sheet 5 to a stretched tension member 3 so as to form an edge 7 of sheet 5 led by tension member string 3, moving tension member 3 with sheet 5 coupled thereto toward the excrement to be picked up, while keeping tension member 3 in close contact with the surface, slipping sheet 5 between the excrement and the surface through moving tension member string 3 between the pet excrement and the surface, so as to isolate the excrement from the surface with sheet 5 in between, wrapping the excrement by sheet 5, and removing sheet 5, wrapping the excrement and disposing thereof.

In reference to FIGS. 12 and 13, a further embodiment, resembling that of FIG. 1, is presented. Tension member 3 comprises an integral leading edge 103 of sheet 5. Leading edge 103 preferably comprises a toughened material that ensures that the edge 103 is comfortably slipped between the excrement and the surface as explained above. Strip 105 comprises a longitudinally non-elastic and transversely flexible material, such that strip 105 can provide a substantially straight leading edge 103, to the sheet 5, while it is stretched by the bar 27. For ease of manufacture, leading edge 103 may comprise a strip 105, and strip 105 may be thermally welded to sheet 5 at the leading edge 103.

Support member 27 is again in the form of an arcuate member that comprises a flexible bowed bar. The bar comprises a contraction handle 107 extending from the inner side portion 109 of the bar 109 parallel to the upper portion 111 of bar 27 toward the intermediate portion 113 of bar 27. Handle 107 being sized for its forcing by at least one finger of the user, gripping bar 27 toward upper portion 111 of bar 27, thereby temporarily contracting the bar by nearing the tips 29 of bar 111 so that the long handle 107 is forced toward bar 27.

Arcuate member 27 comprises at least one laterally protruding hook element, such as hooks 115 mounted at each of tips 29. Tension member 3, namely—leading edge 103 and strip 105 comprise mating openings 117 at their ends 119. Hooks 115 preferably comprise broadened head portion resembling that of a nail or a thumbtack for keeping openings 117 well seized over hooks 115. It will be appreciated that such structure provides for the loose assembling of tension member 3, or leading edge 103, on arcuate member 27, when member 27 is temporarily forced to contract; and provides for the stretching of the assembled tension member 3 when the contraction force ceases to apply thereto.
